I'm trying to put my data tables into two columns so that they don't take up too many pages. My tables look like this:

\documentclass[a4paper, 12pt]{article}

The tables look fine when I display them in one column, but if I wrap them in

\begin{multicols}{2}
%my table code here
\end{multicols}

my tables disappear. What am I doing wrong?

1 Answer 1

2

The documentation of multicol clearly states that table and figure are not allowed and that they will simply disappear.

Sample documentation

Instead you can use center and the typeset the captions with

 \captionof{table}[short caption]{long caption}
